Who came up with the first phylogenetic tree? Tree of Life diagrams have been around much longer than anyone suspected for being such a new, unique way of classifying organisms. Explore the history of phylogenetics and the biological tree of life.

Binomial Nomenclature is the classic method of taxonomy or classifying scientific organisms. Discovered by Carolus Linnaeus centuries ago, this scientific classification system has stood the test of time. Read on to learn how to find and write scientific names of organisms.

Monophyletic groups share traits in common with one another. These groups share the same common ancestor. Scientists use monophyletic groups to classify organisms based on their shared heritable traits. Trace an organism's place in evolution using a life tree.
